Technologies, challenges and perspectives of biogas production within an agricultural context. The case of China and Africa

Abstract: The use of fossil fuels in modern economies has been a success because of the low cost of fossil resources. However, the depletion of fossil reserves, the increase in waste production and global warming concerns have led to increased research on the production of biofuels from renewable resources. Waste production is steadily increasing in quantity and constantly changing in quality, creating enormous risks for the environment and, consequently, for the health of the population. This situation is much more wor… Show more

“…Methane is such a gas as well. Although produced in natural processes, it is more harmful to the environment because it is 25 times as potent as CO 2 [9]. Methane is released from hard coal deposits during the extraction of that resource [10]; it is also produced as a result of anaerobic fermentation of organic matter generated during food production and processing as well as municipal waste management.…”

“…Methane emitted in natural processes has a negative impact on the environment as it has a carbon dioxide equivalent of 25 times. Methane emissions can be reduced by fermenting the organic matter in biogas plants [1]. Biogas is a mixture of methane (40-85%), carbon dioxide (16-48%), and other gases present in trace amounts.…”

“…As a result of the fermentation of organic material, clean and cheap fuel in the form of biogas is produced. It can be used for heating, lighting, and powering machines [1]. Fermentation, however, is an unstable process as it may be disturbed by an increase in temperature in a fermentation chamber, overproduction of volatile fatty acids, and chemical contamination, e.g., with pesticides or heavy metals [4].…”
